Hi Kanuri

Pls. do the following
1) add a label in ur aspx page
2) modify the code ...

if dr.hasrows = false then
   label1.text = "No Record(s) found for the given criteria!!!"
else
If dr.Read() Then
            dateofarrival.Text = dr(0).ToString().Substring(0).Remove(10)
            noofbeds.Text = dr(5).ToString
            roomno.Text = dr(4).ToString
            bookingname.Text = dr(6).ToString
            designation.Text = dr(1).ToString
            department.Text = dr(2).ToString
            address.Text = dr(3).ToString
            requestedby.Text = dr(7).ToString
